The premise of no problem in the use of any product is processing, so now the steel structure can be used so widely, also because the whole processing process of the structure is rigorous, and in the process of processing, it will generally carry out anti-corrosion work, so as to ensure that the structure will not be corroded in the future use. At present, the structure is commonly used in the processing of anti-corrosion The way is to brush anticorrosive coating. What are the commonly used anticorrosive materials? Let's take a look.
1. For the bridge steel structure, the epoxy zinc rich primer is generally used, the intermediate paint is epoxy micaceous iron intermediate paint, and the top coat is acrylic polyurethane top coat. The advantage of this kind of paint is that the anti-corrosion strength is relatively large, and the thickness of the paint can be confirmed according to the geographical environment conditions, so as to extend the anti-corrosion life of steel members.
2. For steel structure workshop components, the primer is epoxy anticorrosive primer, the intermediate paint is epoxy micaceous iron intermediate paint, and the finish paint is epoxy zinc rich finish. According to the use nature of the plant, for example, the general industrial production plant is different from the chemical plant, and the paint of the general plant is generally three times. For the steel structure workshop under the bad environment, the thickness of anticorrosive paint should be increased.
3. As for non-standard steel members, they are generally made by spraying according to the drawing notes. Before the drawing design, the design institute shall select the anti-corrosion method through the local climate conditions.
To sum up, anti-corrosion coating commonly used in steel structure processing, in fact, in order to achieve good anti-corrosion effect when processing the structure, in addition to the attention when selecting, there are certain requirements for the thickness of the coating, because if the coating thickness is thin or uneven, it will lead to a variety of problems, affecting the normal anti-corrosion work We must pay attention to the methods and steps when painting, so as to ensure that the coating can help the structure to resist corrosion.
